ADJUSTABLE WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 595,724, dated December21, 1897.

Application filed February 23, 1897. Serial No. 624,653. (No model.)

To all whom it may concern.-

Be it known that I, DENNIS F. MOONEY, Jr. a citizen of the UnitedStates, residing at Brooklyn, in the county of Kings and State of NewYork, have invented a certain new and useful Improvement in AdjustableWVindow-Screens, of which the following is a specification.

My invention relates to a new and useful improvement in adjustablewindow-screens, and has for its object to so construct the framework ofsuch a screen as to permit its being permanently placed within theWindowcasing, while at the same time giving free access to the exteriorof the window for cleaning or ventilating purposes or for the hanging ofclothes and the like.

lVith these ends in view this invention consists in the details ofconstruction and combination of elements hereinafter set forth, and thenspecifically designated by the claim.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same, its construction and operation will now be described in detail, referring tothe accompanying drawings, forming a part of this specification, inwhich- Figure 1 represents a window having my improved window-screenapplied thereto, the screen being closed; Fig. 2, a similar view showingthe screen open; Fig.3, a similar View showing the screen opened andshoved to one side in order. that the full space of the frame may beutilized for hanging clothes or similar purposes; Fig. 4, a detailsection showin g the fitting of the screen-frame to the window-casing;and Fig. 5, a vertical section of the swinging frame and stationaryframe, showing the former locked in the latter.

In carrying out my invention as here embodied I provide a rectangularframe A, preferably made so as to fit snugly within the window-casing,and this frame may be secured Within the casing by means of theguidestrips B, or it may be so arranged as to be held in place by theordinary stop-strips of the window.

A swinging frame 0, of rectangular shape, is fitted within the frame Aso as to form close joints when lying in the same plane therewith, andthis last-named frame is adapted to swing within the first-named frameby being pivoted thereto by the snap-bolts D, which latter are actuatedby the springs E, adapted to hold said bolts normally in their distendedposition, and the noses of these bolts when in their normal positionenter the holes or sockets F, which are formed in the top and bottomrails of the outer frame, as clearly shown. Formed in these same railsare grooves G, in which the snap-bolts are adapted to fit and slide,said grooves being of less depth than the sockets, so that when it isdesirable to adjust the screen to the position shown in Fig. 3 this isaccomplished by retracting the bolts by the thu mb-pieces H and forcingthe screen sidewise, while the noses of the bolts slide in the grooves,as will be readily understood.

A suitable netting I is stretched upon the frame 0, so that when saidframe is closed, as shown in Fig. 1, insects will be excluded from theroom, and when in this position the swinging frame may be locked againstmovement by the latches J, pivoted thereto and adapted to enter intoengagement with suitable staples upon the outer frame.

In practice much convenience is had by the use of myimproved screen,since it is not necessary to remove the same'from the window whenclothes are to be hung from said 'window or access therethrough isdesirable for other purposes, since by the swinging of the inner frameupon its pivot-points and sliding it sidewise, as before described, freespace is had.

When for ventilating or other purposes it is desirable to open thescreen, but not necessary to slide it sidewise, this may be accomplishedby simply unlocking thelatches J and turning the inner frame to theposition shown in Fig. 2. g

Another advantage gained by my improvement is that since it is notnecessary to move the outer frame for ordinary purposes the latter maybe fitted more tightly andsnugly to the Window-casing, and thereforemore thoroughly exclude insects which are likely to gain access throughloose joints.

It is also to be noted that should occasion require the inner framecarrying the screen may be entirely removed from the outer frame by theproper manipulation of the bolts D, and when this is done the outerframe may be left in placeas, for instance, in Winter when the screen isnot needed-thus leaving the fittings of the screen, which latter may bereturned to its place in warm weather with but little effort.

The cost of manufacture of a screen made in accordance with myimprovement is but little, if any, in advan cc of an ordinaryscreen, andyet many advantages are gained by its use.

Having thus fully described my invention, what I claim as new and usefulis- In combination, a rectangular frame fitted in a window frame to bein oved vertically, said frame having longitudinal grooves formed in theupper and lower rails thereof and sockets near the center of the groovesof greater depth than the grooves, a second rectangular frame adapted tofit within the first-named frame, spring-pressed bolts secured in thesecond frame, said bolts being adapted to fit in the sockets in thefirst-named frame and by retracting said bolts to slide in said grooves,and a suitable netting secured on the second frame, latches for securingthe frames in the same plane, substantially as described.

In testimony whereof I have hereunto affixed my signature in thepresence of two subscribing witnesses.
